Malignancy, malignant neoplasm and malignant tumor are synonymous with cancer; Malignant ascites; Malignant transformation; Non-oncologic disorders referred to as "malignant" include: Malignant hypertension; Malignant hyperthermia; Malignant otitis externa; Malignant tertian malaria (malaria caused specifically by Plasmodium falciparum)
Potentially-malignant neoplasms include carcinoma in situ. They are localised, and do not invade and destroy but in time, may transform into cancer. Malignant neoplasms are commonly called cancer. They invade and destroy the surrounding tissue, may form metastases and, if untreated or unresponsive to treatment, will generally prove fatal.
The name's etymological origin is the Greek word ὄγκος (ónkos), meaning "tumor", "volume" or "mass". [2] Oncology is concerned with: The diagnosis of any cancer in a person (pathology) Therapy (e.g. surgery, chemotherapy, radiotherapy and other modalities) Follow-up of cancer patients after successful treatment
Carcinoma is a malignancy that develops from epithelial cells. [1] Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal [2] or ectodermal germ layer during embryogenesis.
The dispersed tumors are called metastatic tumors, while the original is called the primary tumor. Almost all cancers can metastasize. [39] Most cancer deaths are due to cancer that has metastasized. [40] Metastasis is common in the late stages of cancer and it can occur via the blood or the lymphatic system or both. The typical steps in ...
A sarcoma is a malignant tumor, a type of cancer that arises from cells of mesenchymal (connective tissue) origin. [1] [2] Connective tissue is a broad term that includes bone, cartilage, muscle, fat, vascular, or other structural tissues, and sarcomas can arise in any of these types of tissues.
Certain benign liver tumors, such as hepatocellular adenoma, may sometimes be associated with coexisting malignant HCC. Evidence is limited for the true incidence of malignancy associated with benign adenomas; however, the size of hepatic adenoma is considered to correspond to risk of malignancy and so larger tumors may be surgically removed.
It is a malignant neoplasm and is one of the most treatable and curable cancers, with a survival rate above 95% if discovered in early stages. [3] Testicular seminoma originates in the germinal epithelium of the seminiferous tubules. [4] About half of germ cell tumors of the testicles are seminomas. [5] Treatment usually requires removal of one ...
